LDAP authentication problem in ASP.NET Core for restricted users (logon workstations) using Novell.Directory.Ldap.NETStandard2_0

I use Novell.Directory.Ldap.NETStandard2_0 package to authenticate users from Active Directory and it works fine for most of users.

using (var cn = new LdapConnection())
{
    cn.Connect(ldapOptions.Host, ldapOptions.Port);
    var userDn = username.IndexOf('@') < 0 ? username + $"@{ldapOptions.Domain}" : username;
    cn.Bind(userDn, password);
    if (cn.Bound)
    {
        result.Result = AuthResult.Succeed;
        result.Message = "Login Successful using LDAP: {0}.";
    }

    return result;
}

The problem is when we need to authenticate users that are restricted to logon to only certain computers in our domain (Active Directory).

I added the computer that host my application (IIS & Win Server 2016) to the list but it still fails and restricted users cannot be authenticated yet.

How can I solve this issue? should I change my code? or Active Directory/IIS settings?

LDAP authentication is generally sourced from the domain controller(s), so the domain controller(s) configured as the LDAP host need to be present in the logon workstations (userWorkstations) list.
